API-DESIGNING - API Designing Training Course


Duration: 2 days
The API Designing course will help you learn and get a hands-on experience creating well-designed, modular API definitions using RAML 1.0 and Anypoint Platform.


  • Translate design requirements into API resources and methods. 
  • Use API designer to create API definitions.  
  • Use RAML to define API resources, methods, parameters, and responses. 
  • Document and test APIs. 
  • Minimize repetition in API definitions using resource types and traits. 
  • Model data in APIs using data types. 
  • Modularize APIs using libraries, overlays, and extensions. 
  • Specify API security schemes.


PART 1: Designing APIs 

Module 1: Introducing RESTful API Design 

  • Describe the common web API formats including SOAP, RPC, and REST 
  • Describe REST API architecture
  • List the rules for retaining REST principles in APIs
  • Describe design-first approach for REST APIs

Module 2: Translating Functional Requirements for APIs 

  • Identify different categories and actions for a REST API
  • Convert categories to resources
  • Select HTTP methods to support the actions on the categories

Module 3: Introducing API-Led Connectivity and the API Lifecycle 

  • Describe the API development lifecycle
  • Explain MuleSoft's API-led connectivity approach
  • Navigate Anypoint Platform
  • Describe the API design lifecycle with Anypoint Platform

PART 2: Defining APIs with the RESTful API Modeling Language (RAML) 

Module 4: Defining API Resources and Methods 

  • Use RAML 1.0 to create API definitions
  • Define resources and methods in RAML API definitions
  • Specify URI parameters for necessary resource methods

Module 5: Specifying Responses 

  • Describe response structure in HTTP methods
  • Use status codes in HTTP responses
  • Add error handling and caching information to HTTP responses
  • Select and specify the types of content returned in HTTP responses

Module 6: Documenting and Testing APIs 

  • Add documentation and description nodes to RAML definitions
  • Use the mocking service to create API endpoints
  • Use the API Console to test API endpoints

Module 7: Making APIs Discoverable 

  • Create API Portals for learning about and testing APIs
  • Customize API Portals with themes
  • Publish API definitions to the Anypoint Exchange for discovery
  • Gather feedback from API consumers

Module 8: Modeling Data 

  • Create datatypes and their properties for resources
  • Create examples for datatypes
  • Include datatypes and examples in resource methods
  • Create scenarios in API Notebook to manipulate data using datatypes and examples

Module 9: Reusing Patterns 

  • Create and reference resource types patterns for reusability
  • Use traits to modularize methods

Module 10: Modularizing APIs 

  • Use libraries for greater API composability
  • Use overlays to internationalize resources 
  • Use extensions to promote portability to test APIs in multiple environments

Module 11: Securing APIs 

  • Define API security requirements
  • Use security schemes to apply resource and method level policies
  • Define custom security schemes for APIs
  • Apply an OAuth2.0 external provider policy to resource methods

Module 12: Enhancing API Responses using Hypermedia 

  • Describe hypermedia
  • Simplify API discoverability using hypermedia
  • Use hypermedia to enhance API responses
  • Modify API definitions to generate state-specific client responses in resource methods

Module 13: Versioning APIs 

  • Explain when and when not to version APIs
  • Describe the methods for versioning APIs
  • Document changes in new API versions using shared API Portals
  • Deprecate older versions of APIs
